PURPOSE: to compare pre-cryo data from oocyte cryopreservation (OC) cycles performed for malignancy (MED) vs. elective deferment of reproduction (DR) or oocyte donation (OD). METHODS: all patients were ≤40 y and underwent standard ovarian stimulation and retrieval. Prior to OC, meiotic spindle (MS) and zona pellucida (ZP) retardance was measured using digital polarized light microscopy (DPLM). RESULTS: of 130 OC cycles, 49 were for MED, 73 for DR, and 8 for OD. Cycles completed for MED had an average of 9 ±1 spindle-positive oocytes with a mean MS retardance of 1.2 ± 02 nm and ZP retardance of 2.1 ± .06 nm, which was clinically comparable to the other groups. CONCLUSIONS: women with malignancy can achieve adequate ovarian response and similar oocyte parameters to those of women undergoing fertility preservation for non-cancer indications. Such information, coupled with the ability to noninvasively study oocyte dynamics, may improve the counseling of cancer patients seeking fertility preservation.
